Abstract
An optical waveguide component, with a pigtail attached thereto, is disclosed in which a portion of a surface of the component is bevelled and a portion of the endface of the pigtail is bevelled. The bevelled portion of the pigtail endface is oriented to be substantially parallel to the bevelled portion of the component surface or is oriented to be open with respect to the component surface. The pigtail endface can be continuously bevelled to form a substantially conical shape on the pigtail endface, wherein the substantially conical shape is offset from the optical axis of the pigtail.
